Answer: x = 4
Step-by-step explanation:
First, we must divide the two, its in a fraction, and as you should know, when we divide exponents, you subtract the exponent on the numerator by the exponent on the denominator. So in this case we are doing 7 - 3 which is equal to 5.
[tex]7^5 = 7^x[/tex]
[tex]7^5 = 7^5[/tex]
Then we still need to subtract [tex]7^1[/tex] from [tex]7^5[/tex].
So our answer is [tex]7^4[/tex]
Answer: x = 4
